Question

what is the distance bet. two parallel tangents of a circle having radius 4.5 cm ?
​

Answer 1

Answer:

9 cm

Step-by-step explanation:

9cm because tangent is parallel and distance between them is equal to diameter and diameter is 2 times radius, which is 2 times 4.5cm which is equal to 9cm

Answer 2

step-by-step explanation-:

⇒  O is the center of the circle.

⇒  l and m are two parallel tangents of the circle.

⇒  Radius of the circle =4.5cm

⇒  AB is distance between two parallel tangents.

⇒  AB=OA+OB=4.5cm+4.5cm

∴   AB=9cm

∴  Distance between the parallel tangents l and m is 9cm.
